Application tiled March 31,1887. Serial No. 233,231. (No model.)

jects of my invention are lto produce better work and at less cost.

In the accompanying drawings, Figure 1 is a side elevation of my machine, partly in section. Fig. 2 is an enlarged plan view of the die of said machine, together with a wheel and pinion placed thereon, and a horizontal sec' tional view of the centering-prongs. Fig. 3`

is an enlarged vertical section, partly in elevation, of parts of my machine and said Wheel and pinion, the plane of section being taken on line .r w, Fig. l; and Fig. 4 is avertical section cfa modified form of die, together with a wheel and an elevation of the pinion.

A designates the die,having a central socket for receiving and holding the part to which the wheel B is to be staked or fastened. As shown, that partis the pinion a, having a tenon at its upper end. The socket in the die is of such relative depth to the pinion that the shoulder of the tenon will be fully as high as the surrounding upper face of the die. In the preferred form this die is also provided with a gage-pin, b, Fig. 2, for the purpose of setting the spokes of the wheel in a given position over the die. In the section shown in Fig. I this pin would notbe seen, as it is on the front part of the de5but its position is indicated by broken lines in said figure. The die A is also provided with three openings, c, to permit the centering-prongs d to pass inside the rirn of the wheel A, as shown in Figs. 2 and 3. The centering-prongs dhave their upper ends rigidly secured in punch-flangef, while their lower ends pass losely through holes in the leveler g. This leveler is yielding and slides freely up and down on the body of the punch or set O, under the punch-angef, and

is forced downward by the spring h. Gruidey pins or screws k, passing through the punchangefand into thelevelerg, limtthe downward movement of said leveler.

The punch C, with the leveler fitted thereon, is secured to or formed on a slide or shaft, D, which is free to be moved up and down in the frame E of the machine, but prevented from turning axially therein, in any ordinarymanner-as, for instance, by means of the slotZ and screw m. The punchslide is also provided with a iiange, G, which serves as a handle, and with a spring, n, to hold the punch and connected parts in their elevated position, as shown in Fig. l. Above the flange or handle is a rod, o, andsliding weightp.

A die and punch for a given Wheel and pinion being in the machine, thepinion is placed in the sccketof the holding-die A, and the wheel B placed on said die and pinion with one spoke against the gage-pin b, as shown in Fig. 2. The operator then grasps the flange or handle and brings the punch-slide down. The centeringprongs, whose ends are beveled oft' a little, enter inside the rim of the Wheel and center it, the prongs being light and springy to better accommodate themselves to the work. The leveler also strikes the face of the wheel and levels it on the tenon, while thev spring allows`it to yield until the end of the punch rests on the end of the tenon, as shown in Fig. 3, the punch, of course, being bored out,so as not to interfere with the pinionshalt. The operator thus holds the punch in place with one hand, while with the other he raises the weight p a given distance, deter-A mined by the position of the collar r and setscrew s, and then lets .it fall, thereby driving the punch against the end of the tenon with sufficient force to spread the metal and fasten the wheel thereon. The parts are then released and return to their normal position, ready for a repetition of the operation.

The centering device consisting of the three yielding prongs, as described, is the preferred one; but it will be observed that it is useful only with wheels so made that the inside of their rim is concentric. In some cases wheels are not thus made, and therefore Ihave shown a centering device in Fig. 4 which centers the wheel from its periphery. In this case the die A has the same central socket for the pinion, and concentric therewith a shallow depression, u, of a diameter that the wheel will just ill. This die will be used in the manner before described with the punch, leveler, slide, and Weight, except that the center- 5 ing-prongs will be omitted.

While I do not wish to limit myself to driving the punch-slide by means of the sliding weight, such Weight is preferred on account of the uniformity in the force of its blow.

I claim as my invention` l. In a device for staking Wheels, the cornbination of the holding-die, a centering device, the yielding leveler, and the sliding,r punch, substantially as described, and for the pur- 15 pose specified.

2. In a device for staking Wheels, the combination of the holding-die with the sliding punch, the yielding leveler, and the centeringprongs, substantially as described, and for the purpose specified.

3. In a device for staking Wheels, the combination of the holding-die, the frame E, the sliding punch, the leveler, the spring n, for elevating said punch, the handle for depressing said punch, and the driving-weight and its 25 guide-rod, substantially as described, and for the purpose specified.
